Not all figures are interesting. I just present some suggestion that may lead to other ideas.
Map of the sampled stations.
Overview of the seaice concentration during the sampling.
Number of measurement each day of the sampling.
Mackenzie river discharge and daily mean air temperature measured at Tuktoyaktuk airport. In (B), the black line is 10 days rolling average.
Nutrients variability across all the legs.
This figure shows the correlation between three indices and the discharge rate of the Mackenzie River, measured n numbers of days prior to the sampling. For example, at x = 0 (i.e. at the date of the sampling), the correlation between POC and river discharge was ~ 0.55. We can also see that the correlation increases to its maximum 6-7 days before the sampling. This means that there is a time lag of ~6-7 days, so the influence of the river on optically active constituents will take effect after 6-7 days.
Correlations between particulate absorption and POC/TPC.
We can look at more variables as needed (open for suggestions).
We can also look at some selected pigments. I do not know much about it, so maybe we can discuss which one could be presented.
